7 простых шагов для создания бота Facebook Messenger на Java

Here is a screencast which shows all the examples we discussed:

You should have a look at Facebook’s Send API for all kinds of replies the bot can send. For example, you can even send a receipt to your user, airline boarding pass and much more.

Conversations

This is a differentiating feature of JBot, with this you can literally talk to your bot and have a conversation. See below for an example as to how your bot sets up a meeting for your team by asking some simple questions one after the other.

/**
 * Type "setup meeting" to start a conversation with the bot. Provide the name of the next method to be
 * invoked in {@code next}. This method is the starting point of the conversation (as it
 * calls {@link Bot#startConversation(Event, String)} within it. You can chain methods which will be invoked
 * one after the other leading to a conversation.
 *
 * @param event
 */
@Controller(pattern = "(?i)(setup meeting)", next = "confirmTiming")
public void setupMeeting(Event event) {
    startConversation(event, "confirmTiming");   // start conversation
    reply(event, "Cool! At what time (ex. 15:30) do you want me to set up the meeting?");
}

/**
 * This method will be invoked after {@link FbBot#setupMeeting(Event)}. You need to
 * call {@link Bot#nextConversation(Event)} to jump to the next question in the conversation.
 *
 * @param event
 */
@Controller(next = "askTimeForMeeting")
public void confirmTiming(Event event) {
    reply(event, "Your meeting is set at " + event.getMessage().getText() +
            ". Would you like to repeat it tomorrow?");
    nextConversation(event);    // jump to next question in conversation
}

/**
 * This method will be invoked after {@link FbBot#confirmTiming(Event)}. You can
 * call {@link Bot#stopConversation(Event)} to end the conversation.
 *
 * @param event
 */
@Controller(next = "askWhetherToRepeat")
public void askTimeForMeeting(Event event) {
    if (event.getMessage().getText().contains("yes")) {
        reply(event, "Okay. Would you like me to set a reminder for you?");
        nextConversation(event);    // jump to next question in conversation  
    } else {
        reply(event, "No problem. You can always schedule one with 'setup meeting' command.");
        stopConversation(event);    // stop conversation only if user says no
    }
}

/**
 * This method will be invoked after {@link FbBot#askTimeForMeeting(Event)}. You can
 * call {@link Bot#stopConversation(Event)} to end the conversation.
 *
 * @param event
 */
@Controller
public void askWhetherToRepeat(Event event) {
    if (event.getMessage().getText().contains("yes")) {
        reply(event, "Great! I will remind you tomorrow before the meeting.");
    } else {
        reply(event, "Okay, don't forget to attend the meeting tomorrow :)");
    }
    stopConversation(event);    // stop conversation
}
